MEMBRANE LIQUID-LIQUID EXTRACTION SYSTEM COMPRISING FLOW CHANNELS

摘要

Liquid-liquid extraction elements are described. A liquid-liquid extractionelement includes a first layer pair and a second layer pair disposed adjacentthe first layer pair forming a stack of layers. The first layer pair includesa first polymeric microporous membrane, and a first flow channel layeroriented in a first flow direction having a fluid inlet and a fluid outletdisposed on first opposing sides of the extraction element. The second layerpair includes a second polymeric microporous membrane and a second flowchannel layer oriented in a second flow direction different than the firstflow direction and having a fluid inlet and a fluid outlet disposed on secondopposing sides of the extraction element. The first microporous membrane isdisposed between the first flow channel and the second flow channel. Methodsof extracting a dissolved solute from a first liquid to a second liquid arealso described.
